Update eh !
tank going OK at this stage, settling down, had a serious outbeak of GHA which is getting under control now.
2x54w T5's working well
lots of zoa's which need fragging this weekend, also sinulara which needs fragging this week.
Not at all happy with the overflow..... sounds like a toilet without a valve installed but with a valve my RO chamber dumps too much water into the DT... so trying to get around that .... also i have durso in the DT, which obviously has resulted in VERY poor skimming, so i need to build a propper overflow box.
getting there slowly !
